Broken pipe错误后Tomcat servlet映射错误

【中文标题】Broken pipe错误后Tomcat servlet映射错误

【英文标题】：Tomcat servlet mapping error after Broken pipe error

【问题描述】：

我们已经在 Tomcat 版本 7.0.23 中实现了 Servlet 3.0 AsyncContext。

它正在RHEL 6.1 using OpenJDK version 1.6.0_24,64-bit 服务器中运行

该应用在大部分情况下都运行良好。 当网络出现一些干扰时，来自服务器的更新无法到达客户端，因为存在“ClientAbortException: java.net.SocketException: Broken pipe”异常。被捕获并忽略。

这发生在一行中，

asyncContext.getResponse().getWriter().println(updateStr);

在这个 Tomcat 发疯并将 URL 路由到意外的 servlet 之后。 例如，使用 /query 映射到名为 SessionManager 的 servlet，URL mysite.com/index.html 被路由到 SessionManager servlet。 只有重启tomcat才能解决问题。

关于为什么会发生这种情况以及如何解决这个问题的任何指示？

只是为了添加更多数据，以下是异常的堆栈跟踪。

【问题讨论】：

您好，您找到解决方法或原因了吗？

【参考方案1】：

这听起来像是 Tomcat 的一个错误。

首先，我会尝试更新到 Apache Tomcat 7.0.64。

其次，我会尝试更新到 Java 6u45。

【参考方案2】：

我们在服务器端遇到了类似的问题。事实证明，我们作为响应发送的数据集在过滤级别被阻止，因为数据非常庞大，并且在这个级别爆炸了。

@Component
public class TrackingFilter implements TraceRepository, Filter 
/**
* Few other business relarted code
*
byte[] bytes = pw.toByteArray();
response.getOutputStream().write(bytes);
